ASoC: meson: aiu: Validate written enum values

Noroxi assessment

Priority: Monitor (action score 29/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0965892cc486ca554d72eeb62d85ccf8d0137a5a, 8a6d6735e7c02e88841cca1497ff3d8089f2ef24, 90703664dbc5a4bf3d84f649404318f3cafdbe69.

Low priority for now. Upgrade to Linux Linux 0965892cc486ca554d72eeb62d85ccf8d0137a5a, 8a6d6735e7c02e88841cca1497ff3d8089f2ef24, 90703664dbc5a4bf3d84f649404318f3cafdbe69 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ASoC: meson: aiu: Validate written enum values The AIU HDMI and internal codec mux put callbacks use the written enum value with snd_soc_enum_item_to_val() before checking whether the value is valid for the enumeration. Reject out-of-range values before converting the enum item, matching the validation already done by the G12A HDMI and internal codec mux controls.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Bug bounty scope

Technical details

Attack conditions

  • Someone with local access to the system can trigger it.
  • A low-privileged account is enough.
  • No user action is required.
